Definitions

  • the invention relates to a disk arrangement with a disk with a low-E coating and a capacitive switching region, and to a method for the production thereof.
  • the interior of a motor vehicle or a building can become very hot in summer at high ambient temperatures and intense direct sunlight. For example, if the outside temperature is lower than the temperature in a vehicle interior, which occurs especially in winter, a cold vehicle window acts as a heat sink, which is perceived by the occupants as unpleasant. Also, a high heating power of the air conditioning system must be provided in order to avoid a cooling of the interior via the vehicle windows.
  • Thermal radiation-reflecting coatings so-called low-E coatings
  • low-E coatings are known, for example, from WO 2013/131667 A1, US 201 10146172 A2, EP 1 218 307 B1, EP 2 247 549 A2, WO 2014/127867 A1 and WO 2014/127868 A1.
  • Such a low-E coating reflects a considerable part of the solar radiation, in particular in the infrared range, which leads in summer to a reduced heating, for example of the vehicle interior.
  • the coating also reduces the emission of long-wave thermal radiation of a heated disc into the vehicle interior when the coating is applied to the surface of a disc facing the vehicle interior.
